Open Source Android KCP Apps

yasio is a lightweight C++ asynchronous socket I/O library for client applications across desktop, mobile, game, and embedded-style environments. It supports Windows, macOS, iOS, Android, OHOS, Linux, FreeBSD, Solaris, and other Unix-like systems. The library focuses on practical cross-platform networking rather than tying developers to a single engine or operating system. It is used in game and multimedia projects and provides integrations or demos for Unity, Unreal Engine, xlua, axmol, and related development stacks. yasio can be used for TCP, UDP, SSL, IPv6, KCP, and multi-threaded networking scenarios. It is useful for developers who need a portable socket layer that works consistently across games, apps, tools, and custom client software.

kcptun for Android is an Android plugin that brings kcptun acceleration support to the Shadowsocks Android ecosystem. It is designed as a SIP003 plugin, which means it can be used alongside shadowsocks-android rather than functioning as a standalone VPN client. The project packages kcptun client functionality for Android users who want to route Shadowsocks traffic through a KCP-based transport layer. Its main purpose is to improve connection behavior in unstable or high-latency network conditions by using kcptun’s reliable UDP tunneling approach. The repository includes Android application code, plugin integration files, and localization support through the same translation process used by shadowsocks-android. It is best understood as a specialized networking companion for users who already understand Shadowsocks and kcptun configuration.
